I bought a used Xbox 360 from someone who was abandoned and I didn't see until I got home that the controllers looked like they had been buried in the mud for 1000 years. I tried to get them clean but finally gave up and bought cases. They were cheap so I took them. They were a bit difficult to put on and one was a little torn in the process. They don't look stunning, but they're definitely better than looking at crispy controllers.
